Am I pregnant or is it just smthn else? TTC?

Before any rude commentars decide to comment, I know I can buy a pg test and find out. It might just be too early IF I am. So, I am at 3dpo right now and at 1dpo, I noticed that my bbs were tender, especially at my and they still are. Also, I had a runny nose for a couple of days this week. I have been both restless and tired. During the day, I am tired but at night, I cannot sleep. Today, I took a 2 hour nap and when I woke up, I was feeling extrememly sick. Its about 40 minutes later and I am still feeling sick. I also have gas in my stomach and have a yeast infection. I have been TTC and bd around the time of oulation and before that. Thanks for any thoughts. PS people have been known to get pg symptoms as early as 1dpo. Thanks
